PURPOSE:To provide a bearing abrasion loss detecting device capable of directly and accurately detecting abrasion loss of a bearing, being attached easily and having high reliability. CONSTITUTION:Thin film resistive bodies 12 having a fixed value of resistivity are laminated in an insulator 14 at a fixed diestance L, and both ends of respective thin film resistive bodies 12 are but in parallel connection by a connecting wire 13 and formed in an abrasion sensor 11. This abrasion sensor 11 is implanted in a bearing 1 so as to be worn together with a metal 3, and abrasion amount of the metal 3 is calulated and displayed by means of a calculation display means 17 by correcting the value of resistivity which follow as tempreature change by meanus of the resistance change and a temperature detected value of a temperature sensor 16. The abrasion amount can be easily and accurately detected only by implanting the absrasion sensor 11 in the bearing 1, thereby the time for exchanging the metal 3 of the bearing 1 can be knows by always monitoring the bearing abrasion amocnt, so that the generation of any trouble can be prevented in advance. |
